Dow Corning 982 


Dow Corning 982 Silicone Insulating Glass Sealant is a two-part silicone sealant. As supplied, the base component, Dow Corning 982 Silicone Insulating Glass Sealant-Base, is a smooth, white paste. The curing agent component, Dow CorningĀ® 2-Part Curing Agent, is a pourable liquid available in black or gray. Once mixed at the proper base-to-curing agent ratio, the material cures to a durable, high-modulus, flexible silicone seal that is chemically stable.

Dow Corning 982 Silicone Insulating Glass Sealant retains design properties and maintains adhesion to substrates, keeping insulated glass seals weatherproof, after years of exposure.
